[A Surgical Case Report of Gastric Cancer Patient with Severe COPD Successfully Controlled by Preoperative Pulmonary Rehabilitation].

A 72-year-old man with a history of chronic obstructive pulmonary disease(COPD)was diagnosed with type 3 gastric cancer at the posterior wall of the gastric body. Although there was no distant metastasis in preoperative imaging tests, pulmonary function test revealed severe obstructive ventilatory impairment, suggesting that the patient had high risks of perioperative pulmonary complications. After treatment for COPD and preoperative pulmonary rehabilitation under hospitalization for 2 weeks, laparoscopic distal gastrectomy plus D2 lymphadenectomy plus Roux-en-Y reconstruction was performed.

Timing of Uterine Artery Embolization for Leiomyoma during the Menstrual Cycle.

Purpose: To investigate differences in outcomes of uterine artery embolization (UAE) for leiomyoma when performed during different phases of the menstrual cycle.

Materials And Methods: In this single-institution retrospective analysis, 111 premenopausal patients (median [range] age, 44 [33-52] years) undergoing UAE for symptomatic leiomyoma between June 2014 and February 2020 were included. Twenty-one patients underwent UAE in the menstrual phase (the early follicular phase), 27 in the late follicular phase, and 63 in the luteal phase.

Nerve Splitting and Vascular Transposition for Trigeminal Neuralgia Attributed to Nerve Penetrating Trigeminocerebellar Artery: 2-Dimensional Operative Video.

The trigeminocerebellar artery (TCA) is an infrequent anatomic anomaly of the branches originating from the basilar artery. It is clinically identifiable by the presence of the ipsilateral superior cerebellar artery and the anterior inferior cerebellar artery, and its course from the basilar artery to the cerebellar hemisphere. Because of its anatomic proximity to the trigeminal nerve root, the TCA often causes trigeminal neuralgia (TGN).

Machine learning-based prediction models for accidental hypothermia patients.

Background: Accidental hypothermia is a critical condition with high risks of fatal arrhythmia, multiple organ failure, and mortality; however, there is no established model to predict the mortality. The present study aimed to develop and validate machine learning-based models for predicting in-hospital mortality using easily available data at hospital admission among the patients with accidental hypothermia.

Method: This study was secondary analysis of multi-center retrospective cohort study (J-point registry) including patients with accidental hypothermia.

The therapeutic strategy for advanced gastric cancer with pyloric stenosis and liver metastasis; successfully treated by gastro-jejunal bypass and chemotherapy first, followed by curative R0 resection.

Background: The indication of surgical resection for liver metastasis from gastric cancer (GC) is still limited and controversial because of its more aggressive oncological characteristics than liver metastasis from colorectal cancer. Pyloric stenosis causes an inadequate oral intake and malnutrition in GC patients. We herein report a case of GC with these two factors that was successfully treated by the combination of gastro-jejunal bypass and chemotherapy, followed by curative R0 resection.

Petrosal Vein Involvement in Neurovascular Conflict in Trigeminal Neuralgia: Surgical Technique and Clinical Outcomes.

Background: Contact of the main stem of the petrosal vein (PV) to the nerve root is a rare cause of trigeminal neuralgia (TGN). The implication of the PV in relation with neurovascular contact (NVC) is not fully understood.

Objective: To assess the operative procedures in microvascular decompression (MVD) in patients with PV involvement in the long-term.

Posterior lumbar subcutaneous edema as the rare sign of IgA vasculitis (Henoch-Schönlein purpura): A case of a child.

Posterior lumbar subcutaneous edema (PLSE) is often found on MRI in adults with obesity or various lumbar conditions. We report a case of a 6-year-old boy with IgA vasculitis (Henoch-Schönlein purpura) along with PSLE observed on CT and MRI. The finding is markedly rare in patients with IgA vasculitis, with only limited cases previously reported in the literature.

Radiologic results of additional single screw fixation with lateral locking plate after hybrid closed-wedge high tibial osteotomy.

Background: Hybrid closed-wedge high tibial osteotomy (hybrid CWHTO) is an effective surgical treatment for medial compartment osteoarthritis of the knee. Our study investigated whether the combination of a lateral locking plate and a single medial screw promoted bone union after hybrid CWHTO.

Methods: The study cohort consisted of 30 patients (15 men and 15 women) who underwent hybrid CWHTO for medial compartment osteoarthritis or spontaneous osteonecrosis of the knee.

Complete relief of vasospasm - Effect of nicardipine coating during direct clipping for the patient with symptomatic vasospasm of subarachnoid hemorrhage.

Background: Some patients come to the hospital presenting with ischemic neurological deficits due to postsubarachnoid hemorrhage (SAH) cerebral vasospasm. In such a situation, neurosurgeons tend to avoid direct clipping, since mechanical irritation to the vessels could worsen the vasospasm and exacerbate ischemic symptoms. The optimal timing of direct clipping in patients with evidence of vasospasm is undetermined.

Lumboperitoneal Shunt Surgery Using Valve Implantation on the Paravertebral Spinal Muscle.

Background: One possibly problematic feature of lumboperitoneal shunt (LPS) placement involves inaccuracy in handling the shunt valve compared with ventriculoperitoneal shunt. Flushing the valve to ascertain shunt patency and adjusting the valve pressure in LPS are often more difficult than with ventriculoperitoneal shunt, particularly when the valve is routinely located in abdominal fat. To overcome this inaccuracy, we applied a simple alteration to the usual LPS procedure.

Care at critical care medical centers is associated with improved outcomes in patients with accidental hypothermia: a historical cohort study from the J-Point registry.

Aim: The recommendation that patients with accidental hypothermia should be transported to specialized centers that can provide extracorporeal life support has not been validated, and the efficacy remains unclear.

Methods: This was a multicenter retrospective cohort study of patients with a body temperature of ≤35°C presenting at the emergency department of 12 hospitals in Japan between April 2011 and March 2016. We divided the patients into two groups based on the point of care delivery: critical care medical center (CCMC) or non-CCMC.

Does Transport by a Doctor Helicopter Affect Blood Pressure in Stroke Patients?

Objective: Herein we investigate whether transportation by doctor helicopter (DH) affects blood pressure (BP) in stroke patients.

Methods: A total of 119 stroke patients treated by the DH between April 2015 and March 2019 were analyzed. The average BP before and after admission to the DH was compared for all stroke patients.

Effect of Lomerizine Hydrochloride on Preventing Strokes in Patients With Cerebral Autosomal Dominant Arteriopathy With Subcortical Infarcts and Leukoencephalopathy.

Background: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an orphan disease clinically characterized by migraine, recurrent strokes, and dementia. Currently, there are no disease-modifying therapies, and it is difficult to prevent cerebral ischemic events in CADASIL patients by conventional antithrombotic medication. We hypothesized that an antimigraine agent, lomerizine hydrochloride, may prevent strokes in CADASIL patients, based on its effect on increasing cerebral blood flow.

Surgical Management for Craniocervical Junction Arteriovenous Fistula Targeting the Intradural Feeder.

Background: Craniocervical junction arteriovenous fistula (CCJAVF) has a variety of forms, including dural and perimedullary arteriovenous fistulas. Owing to this anatomic variety, the terminologies for classifying CCJAVF, most of which aim to describe angiographic structures, have yet to be firmly established, and the current taxonomic classifications do not facilitate surgical strategies. Herein we focused on the existence of intradural feeder vessels, allowing the identification of 2 types of CCJAVF.

Microvascular decompression for trigeminal neuralgia attributable to the vertebrobasilar artery: decompression technique and significance of separation from the nerve root.

Background: Separation of the vertebrobasilar artery (VBA) from the trigeminal nerve root in microvascular decompression (MVD) is technically challenging. This study aimed to review the clinical features of VBA involvement in trigeminal neuralgia and evaluate surgical decompression techniques in the long term.

Methods: We retrospectively reviewed the surgical outcomes of 26 patients (4.

Aneurysm of Distal Medial Lenticulostriate Artery: Report of 2 Cases.

Background: Aneurysms originating from the distal portion of the lenticulostriate artery (LSA) are uncommon. Distal medial LSA (MLSA) aneurysms are particularly uncommon when compared with distal lateral LSA aneurysms, and their clinical features are unclear. Here, we present 2 patients with aneurysms of the distal MLSA who exhibited hemorrhages of the caudate nucleus and intraventricular region (intraventricular hemorrhage [IVH]).

Managing intervention for severe intraventricular hemorrhage casting in moyamoya disease: Report of two cases.

Introduction: When severe intraventricular hemorrhage (IVH) casting in moyamoya disease (MMD) is mentioned, experts advocate not to evacuate the IVH in acute phase. However, the devastating outcomes derived from this empirical rule have not been addressed. Herein, we report two MMD cases undergoing obliteration of ruptured aneurysm and early complete aspiration of severe IVH casting, and showed good outcomes.

Organized Chronic Subdural Hematoma Treated with Middle Meningeal Artery Embolization and Small Craniotomy: Two Case Reports.

The most preferred treatment for organized chronic subdural hematoma (OSDH) remains controversial. Although a large craniotomy has been reported to be necessary and effective for the treatment of an OSDH, a craniotomy is associated with postoperative hemorrhagic complications and recurrence. Although middle meningeal artery (MMA) embolization has been reported to be effective for a refractory chronic subdural hematoma (CSDH), its efficacy for an OSDH remains unclear.

Fatal Subarachnoid Hemorrhage: A Rare Presentation of Ruptured A2 Dissecting Aneurysm.

Anterior cerebral artery dissection (ACAD), especially simultaneously presenting with subarachnoid hemorrhage (SAH) and cerebral infarction (CI), is rare. Only a few cases of severe SAH due to ACAD have been reported. Herein, we present an unusual case of severe SAH with simultaneous CI caused by ACAD.

Clinical data on rare case of spontaneous disappearance of intracranial Aneurysm.

The data contained within this paper are related to another paper entitled "Rare Spontaneous disappearance of intracranial aneurysm" (Yokoya et al., 2020). Spontaneous disappearance of an unruptured non-giant aneurysm of the anterior circulation is very rare.
